Aftermarket Steering Knuckles

[skrimgo]

Hi, I am currently in the process of building an R32 Skyline drift car with the intention of occasional street use too (with the likes of an MSNZ authority card / logbook).

I was wondering what the legalities were in regards to aftermarket steering knuckles, designed to correct suspension geometry in lowered cars as well providing more steering lock.

eg.

OR

Thanks in advance.

A custom stub axle such as this would need to go through the Technical Advisory Committee for approval.

So the manufacturer would need to be willing to provide to them, a fair amount of technical and construction detail.
